One could simply increase the chance for mobdrops such as tantrums etc. In the code. Or set that there should already be 4 eyes in the portal.
How do you check whether you are cheating on such speed runs? In the video proof you have to do you do not see the code of the game. How is it checked whether everything in the code is unchanged or whether you are using a modified client? Or do you need a special Speedrun Client? How do they do it?
Well, how many eyes there are in the portal depends on the seed. It is not accidental. So you can see that immediately. Especially when you play set seed, where most people use the same seed.
If someone has increased the chances of drops or something similar, it is difficult to check.
At speedrun.com there are always 1-10 people who are responsible for a game. They take a look at the submissions and if they don't see the wrong thing straight away, they go online.
There have been cases where years of spliced speedruns were considered a world record.
Splicing means that you divide your speedrun into sections, do them all individually with a very good time, and then cut them together. This is a very popular trick that works for all games. Some also accelerate a video by 1% or similar. You can only do something like this later.
I don't know if it depends on the seed if I think about it.
Yes, the number of eyes in the portal depends on the seed. And the mobdrops are not, they are random. That's right.
So could I increase the chances of mobdrops or the Enderman spawn rate in the code without them noticing? ^^
You could try If you do it discreetly, you may not notice it, if you make it too obvious, you will.
The people who run these games are experienced speedrunners themselves, so they know what is realistic.
